The invention relates to a single-phase capacitive voltage division electronic voltage transformer which comprises a shell, a base, a support, intermediate electrodes, an insulating support, a high-voltage electrode, a junction box, a disc insulator, an explosion-proof device, an upper shielding ring, a lower shielding ring and a grounding electrode. The shell is fixedly arranged on the base, the insulating support is fixedly arranged on the base, the grounding electrode is fixedly arranged on the insulating support, the disc insulator is fixedly arranged on the shell, the high-voltage electrode is connected with the disc insulator and is arranged in inner cavities of the intermediate electrodes, and the intermediate electrodes, the upper shielding ring and the lower shielding ring are respectively fixedly arranged on the grounding electrode. The single-phase capacitive voltage division electronic voltage transformer has the advantages that as the intermediate electrodes, the upper shielding ring, the lower shielding ring and the shell are made of aluminum alloy materials with low expansion coefficients, fluctuation of detected data due to expansion of the materials is reduced; and the high-voltage electrode is of an arc-shaped cylindrical structure, ports of the intermediate electrodes and ports of the upper and lower shielding rings are in arc-shaped transition, and accordingly point discharge is reduced.
